VMA offsets are 64 bits. Plane surface offsets are in ggtt and the hardware register to set this is thus 32 bits. Be explicit about these and convert carefully to from vma to final size. This will make sparse happy by not creating 32bit pointers out of 64bit vma offsets. Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Signed-off-by:

There is known issue on GT interrupt delivery with DC6 and firmwares <1.21. There is a suspicion that this causes spurious gpu hangs on driver init and with some workloads, as upgrading the firmware to 1.21 makes these problems disappear. As of now the current version included in distribution firmware packages is very like to be 1.19. Play it safe and refuse to load a firmware version that may affect gpu side stability. With < 1.23 there is a palette and dmc ram corruption issue so blacklist anything below that. v2: Refuse to load fw instead of notifying the user v3: Rebase on header version changes v4: Refuse to load anything less than 1.23 v5: Give enough information for user for finding correct fw (Chris) v6: better url and formatting (Chris) v7: move error log for each fail path (Mika) bail out earlier in load path (Imre) v8: Fix the version check (Imre) Cc: Animesh Manna <animesh.manna@intel.com> Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Dave Gordon <david.s.gordon@intel.com> Cc: Arun Siluvery <arun.siluvery@linux.intel.com> Cc: Imre Deak <imre.deak@intel.com> Cc: Patrik Jakobsson <patrik.jakobsson@linux.intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@gmail.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> References: https://01.org/linuxgraphics/downloads/skldmcver121 References: https://01.org/linuxgraphics/downloads/skylake-dmc-1.23 Testcase: igt/gem_exec_nop Signed-off-by: -

We had two failure modes here: 1. Deadlock in intelfb_alloc failure path where it calls drm_framebuffer_remove, which grabs the struct mutex and intelfb_create (caller of intelfb_alloc) was already holding it. 2. Deadlock in intelfb_create failure path where it calls drm_framebuffer_unreference, which grabs the struct mutex and intelfb_create was already holding it. [Daniel Vetter on why struct_mutex needs to be locked in the second half of intelfb_create: "The vma [for the fbdev] is pinned, the problem is that we re-lookup it a few times, which is racy. We should instead track the vma directly, but oh well we don't."] v2: * Reformat commit msg to 72 chars. (Lukas Wunner) * Add third failure mode. (Lukas Wunner) v5: * Rebase on drm-intel-nightly 2015y-09m-01d-09h-06m-08s UTC, rephrase commit message. (Jani Nicula) v6: * In intelfb_alloc, if __intel_framebuffer_create failed, fb will be an ERR_PTR, thus not null. So in the failure path we need to check for IS_ERR_OR_NULL to avoid calling drm_framebuffer_remove on the ERR_PTR. (Lukas Wunner) * Since this is init code a drm_framebuffer_unreference should be all we need. drm_framebuffer_remove is for framebuffers that userspace has created - and is getting somewhat defeatured. (Daniel Vetter) v7: * Clarify why struct_mutex needs to be locked in the second half of intelfb_create.

In intelfb_alloc(), if the call to intel_pin_and_fence_fb_obj() fails, the bo is unrefed twice: By drm_framebuffer_remove() and once more by drm_gem_object_unreference(). Fix it. Reported-by:
-
Lukas Wunner authored
Currently when allocating a framebuffer fails, the gem object gets unrefed at the bottom of the call stack in __intel_framebuffer_create, not where it gets refed, which is in intel_framebuffer_create_for_mode (via i915_gem_alloc_object) and in intel_user_framebuffer_create (via drm_gem_object_lookup). This invites mistakes: __intel_framebuffer_create is also called from intelfb_alloc, and as discovered by Tvrtko Ursulin, a double unref was introduced there with a8bb6818 ("drm/i915: Fix error path leak in fbdev fb allocation"). As suggested by Ville Syrjälä, fix the double unref and improve code clarity by moving the unref away from __intel_framebuffer_create to where the gem object gets refed. Based on Tvrtko Ursulin's original v2. v3: On fb alloc failure, unref gem object where it gets refed, fix double unref in separate commit (Ville Syrjälä) v4: Lock struct_mutex on unref (Chris Wilson) v5: Rebase on drm-intel-nightly 2015y-09m-01d-09h-06m-08s UTC, rephrase commit message (Jani Nicula) Tested-by:

Move register write from intel_dp_update_link_train() into intel_dp_set_signal_levels(). This creates a better split between the i915 specific code and the generic link training part. Note that this causes an extra register write in intel_dp_reset_link_train(), since both intel_dp_set_signal_levels() and intel_dp_set_link_train() write to the DP register. Signed-off-by:

Move the call to intel_dp_get_adjust_train() out of intel_dp_update_link_train() and call it instead from the clock recovery and channel equalization features. A follow up patch will remove the DP register write from that function, so that it handles only the DPCD write. Signed-off-by:

It just makes the code more confusing, so just reference intel_dp_>DP directly. Note that this also fix a bug where the value of intel_dp->DP could be different than the last value written to the hw, due to an early return that would skip the 'intel_dp->DP = DP' line. v2: Don't preserve old DP value on failure. (Sivakumar) - Don't call drm_dp_clock_recovery_ok() twice. (Sivakumar) - Keep return type of clock recovery and channel equalization functions as void.

SWF18 is set if the display has been initialized by the pre-os. It also gives what configuration is enabled on which pipe. In skl_sanitize_cdclk, the DPLL sanity check can pass even if GOP/VBIOS is not loaded as BIOS enables DPLL for integrated audio codec related programming. So fisrt check if SWF18 is set and then follow through with other DPLL and CDCLK verification. If not set then for sure we need to sanitize the cdclock. v2: Update the commit message for clarity (Siva) v3: Correct the mask to check for bits[23:0] instead of only bits[16:0]. Had missed checking for PIPE C altogether. Remaining are reserved (Siva) v4: Use ILK_SWF macro for SWF register definitions.

Matt Roper authored
BXT CRTC scaling uses the same gen9 codepaths as SKL; these codepaths store panel fitter information in pipe_config->pch_pfit. However since HAS_PCH_SPLIT() is false for BXT we never actually wind up filling in this structure (we wind up filling in pipe_config->gmch_pfit instead, which is ignored when we go to program the hardware). Make sure we always take the PCH code path on gen9+ platforms. v2: Use HAS_GMCH_DISPLAY() to more cleanly describe the platforms that actually want to use GMCH-style panel fitting.

struct_mutex is being locked for every plane in intel_prepare_plane_fb and intel_cleanup_plane_fb. Require the caller to hold the mutex, and only acquire the mutex for each helper call. This way the lock only needs to be acquired twice in ->atomic_commit(). Once for pinning new framebuffers at the start, the second time for unpinning old framebuffer. Changes since v1: - Use mutex_lock_interruptible instead of i915 variant, to prevent a deadlock when called from the reset code. Changes since v2: - Clarify struct_mutex is locked by the caller.

Kabylake is a Intel
® Processor containing Intel® HD Graphics following Skylake. It is Gen9p5, so it inherits everything from Skylake. Let's start by adding the platform separated from Skylake but reusing most of all features, functions etc. Later we rebase the PCI-ID patch without is_skylake=1 so we don't replace what original Author did there. Few IS_SKYLAKEs if statements are not being covered by this patch on purpose: - Workarounds: Kabylake is derivated from Skylake H0 so no W/As apply here. - GuC: A following patch removes Kabylake support with an explanation: No firmware available yet. - DMC/CSR: Done in a separated patch since we need to be carefull and load the version for revision 7 since Kabylake is Skylake H0. v2: relative cleaner commit message and added the missed IS_KABYLAKE to intel_i2c.c as pointed out by Jani.
